is mostly because it lets people get to 60 and still have no idea how to play their class.
Running dungeons to get prebis on my latest alt has been a slog of awful tanks that don’t know how to tab-sunder, healers that spam themselves OOM every single pull even though the tank isn’t being hit hard, mages that are super slow on sheeping (if they even sheep at all) etc. etc.
If I were to fix this, I’d just make it so that if there’s more than 10 levels of difference between the lowest and highest level party members, exp gain from kills is reduced by 90%. “Boosting” just goes against the spirit of the game and raises clueless players that don’t know how to play because their 10-60 experience was just /afk’ing in dungeons.
